NEC has some pretty crazy ideas when it comes to smartphone design — as we discovered when we checked out the dual-screen Medias W at Mobile World Congress back in February. And its latest offering is just as outlandish.

As successor to the hugely successful Galaxy S III, the Galaxy S4 always had big boots to fill — but it appears to be doing that with ease. In just four days last month, Samsung shipped a staggering 4 million Galaxy S4 handsets. It’s now on track to ship 10 million by the end of May.

OK, so maybe not a huge surprise, but Google is said to launch a paid, subscription-based music service, like Rdio or Spotify, as soon as this week at the Google I/O conference, reports the Wall Street Journal.

According to “people familiar with the matter,” says the WSJ, the announcement of the new service could happen as soon as tomorrow, when Google hosts it’s annual I/O developer conference. The WSJ says that Google has previewed new music initiatives at I/O in the past, so it might just announce the streaming service there, as well.

Pinterest has updated its official app on both Android and iOS with several big features. Users can now receive push notifications for things like comments, mentions, and repins. “@” mentions have also been added for messaging friends on the service. Pinterest will now show you search suggestions as you type, like Google.

An iOS exclusive feature is the ability to send a pin to someone directly within the app. You can also invite friends to pin on group boards.

Pinterest is a free download and today’s update is available in Google Play and the App Store.
